How to use redis as mediawiki cache backends

# 如果已经使用过 apcu 作为缓存，要先去除 apcu 缓存
grep -r apc /etc/php/8.2/
sudo emacs /etc/php/8.2/mods-available/apcu.ini # 注释掉对 apcu 的调用

# 进 LocalSettings.php 取消对 CACHE_ACCEL 的调用
## Shared memory settings
## $wgMainCacheType = CACHE_ACCEL;
## $wgMemCachedServers = [];

# 安装并配置 redis 作缓存后端
sudo apt install redis-server php-redis

# 编辑 LocalSettings.php
$wgObjectCaches['redis'] = [
    'class'                => 'RedisBagOStuff',
    'servers'              => [ '127.0.0.1:6379' ],
    // 'connectTimeout'    => 1,
    // 'persistent'        => false,
    // 'password'          => 'secret',
    // 'automaticFailOver' => true,
];

$wgMainCacheType    = 'redis';
$wgParserCacheType  = 'redis';        // 可选
$wgMessageCacheType = 'redis';        // 可选
// 若使用新版 API，可直接写 'redis'
// $wgMainCacheType = 'redis';
